Pamela Gomez
Federal Aviation Administration (FAA)
WAAS GCCS Team Lead
GNSS In U.S.
•
•
•
U.S. Has Approved Use of Global Positioning System (GPS) For Aircraft Navigation
For Over A Decade
FAA Working With Other U.S. Federal Government Agencies To Insure Modernization
of GPS Improves Aviation Capabilities
FAA Has Commissioned the FAA’s GNSS Space Based Augmentation System (SBAS)
– Wide Area Augmentation System (WAAS)
•
FAA Is Continuing Development Of the GNSS Ground Based Augmentation System
(GBAS)
– Local Area Augmentation System (LAAS)
•
FAA Has Committed To A “Performance Based National Airspace System”
– Fully utilize the capabilities of all equipment aboard the aircraft
– Implement Required Navigation Performance (RNP)
GNSS SBAS (WAAS – In USA)
• Enhances Navigation In All Phases Of Flight
– Enroute, Arrival, and Departure:
• Provides 100% Availability Of GNSS For Even The Most Critical RNP or
RNAV Operations
• Provides Coverage At All Altitudes From 100,000 Feet To The Surface
• Provides Navigation Services To Users That Are Not Currently Served
– Approach:
• Enhances Safety By Providing Vertical Guidance To Every Runway End In
The Coverage Area
• No Ground Hardware Required At Airport
• Allows IFR Operations To All Qualified Airports
SBAS: WAAS Background
•
August 2000: FAA Makes WAAS Available For Non IFR Aviation Use
– Signal Available At Surface For All Users
•
July 2003: Initial Operating Capability (IOC) For All Aircraft Instrument Flight

•
•
Addition of GEO Satellites To Provide At Least Two In View To All
Users Over All CONUS And Alaska
Improvements To Ground Components To Complete “GLS Segment”
